简介：考虑在精炼厂处理的实际粗略的板岩，做合理联合是必要的并且原油相配。为了在柴油应付高蜡内容，为了在柴油应付高蜡内容被建议适当地调整精制过程计划并且在在生产实践被使用以后把添加剂加到精制products.This措施引起了好结果并且满足了商业生产的需要。

简介：二新奇的灰更少添加剂-benzothiazole衍生物包含硼和氯，OBC和BBC，被综合。在在油菜籽的添加剂上油的不同集体比率(RO)的OBC和BBC的tribological表演在一台四球的机器上被检验。油样品润滑的更低的钢球的穿的表面借助于扫描电子显微镜学(SEM)被分析。测试结果显示出那OBC，BBC在底有好溶解度上油，并且能有效地增加基础油的带负担的能力。包含1.5m%BBC的油样品的最大的非抓住负担是1117N，它2.3倍于基础油的。OBC和BBC能改进禁止性能和基础油的热稳定性的反穿和腐蚀，谁的起始的分解温度在350°C上面。然而，在不同集中的OBC和BBC能增加基础油的磨擦系数。油润滑的钢球的SEM形态学取样包含1.5m%添加剂似乎比形成的基础油，和疤的更一致、光滑是很浅的。

简介：催化py-rolysis-maximizing丙烯(TMP)技术独立地由中国石油大学(华东)的州的关键重油实验室开发了的二阶段的起床人的商业测试表明了在受到TMP之上的那大气的残油(AR)能超过18%完成丙烯收益，并且LPG，汽油和柴油机产量的和能接近83%。当重油的FCC或两重棉包线吸引了特殊注意最大化丙烯产量，在最近的年，这处理，因为常规催化裂开技术能仅仅在3%的范围贡献丙烯收益—5%。
